SIGNAL PROCESSING DEVICE, IMAGE READING DEVICE, IMAGE FORMING APPARATUS, INFORMATION PROCESSING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

An image reading device includes: a reading unit in which light receiving elements are arranged in a line along a second direction; and a light source control section that controls emission of the light source members, the light source control section performing control such that light is emitted in a cycle order of the first, second, and third colors on the basis of a reference signal which is output at a preset time interval, and to make a time of emission of the light with the first color close to a time of start of emission of the light with the second color and to make a time of emission of the light with the third color close to a time of end of emission of the light with the second color.

主权项

1. An image reading device comprising:
a light source section that irradiates an original document on which an image is printed, with light, the light source section including a first light source member which emits light with a first color, a second light source member which emits light with a second color different from the first color, and a third light source member which emits light with a third color different from the first and second colors; a reading section that reads the original document by moving in a first direction relative to the original document, the reading section having light receiving elements, which receive light reflected from the original document and are arranged to receive light along a second direction intersecting with the first direction; and a light source control section that controls emission of the light source members, the light source control section performing control such that light is emitted in a cycle order of the first, second, and third colors on the basis of a reference signal which is output at a time interval, and to make a time of emission of the light with the first color close to a time of start of emission of the light with the second color and to make a time of emission of the light with the third color close to a time of end of emission of the light with the second color.
